In core training with 12-20 reps (6-10 SL), what does SL indicate?

• A. Single-leg variations
• B. Super-light repetitions
• C. Strength level
• D. Sequential load

Answer: (A)

SL is standard shorthand for single-leg in many fitness programs. In this core-training notation, 12-20 reps (6-10 SL) means you complete 12–20 total repetitions, with 6–10 of those performed using a single-leg variation. This unilateral approach increases demand on the stabilizing muscles of the core, hips, and ankles, improving balance, coordination, and functional strength. The other options don’t fit common programming shorthand in this context.
